encoder counts and pulses

2004-02-15 Thread whatsthis4
Just a quick question to make sure I understand how quadrature encoders work. On the encoder disk, we have channel A and B. Now if I have an encoder with 2000 counts per revolution does this mean that: 1) every rising and falling edge of channel A and B represents one count of motion? 2) there

Read Trajectory Data Function and 7344 card

2004-02-12 Thread whatsthis4
The Read Trajectory funtion in Flexmotion is apparently able to buffer position data up to 333Hz (3ms sample time). Is this motion card dependent? I read somewhere on the forum that for the 7344 MOTION CONTROLLER, reading position is only possible up to a rate of 100 Hz (10ms sample time)?
